[0002] Chinese Patent Publication No. CN103022820B discloses a connector assembly. An electromagnetic interference gasket is provided between the cage and the heat sink in the retainer assembly. The electromagnetic interference gasket is mechanically connected to the heat sink by interference fit and / or snap fit. However, in such a connector assembly, the electromagnetic interference gasket is fixed to the heat sink and moves with the heat sink. Therefore, when the heat sink is lifted by the plug-in module, a relatively large gap still appears between the heat sink and the opening of the cage. Summary of the Invention

[0003] Therefore, an object of the present invention is to provide a connector assembly that can improve at least one drawback in the prior art.

[0004] Thus, in some embodiments, the connector assembly of the present invention includes a guiding shield, a shielding fence, and a heat sink. The guiding shield has at least one accommodating space, a socket at the front end communicating with the accommodating space, and a wall forming the accommodating space. The wall is formed with a window communicating with the accommodating space. The shielding fence is disposed on the wall of the guiding shield through a fixing structure. The shielding fence has a frame body, and an opening defined by the frame body and corresponding to the window. The heat sink has a surface disposed on the wall, and a heat coupling portion protruding from the surface. The heat coupling portion passes through the opening of the shielding fence and the window into the accommodating space and can move relative to the guiding shield. Moreover, the frame body of the shielding fence is located between the wall of the guiding shield and the surface of the heat sink, and surrounds the window of the wall of the guiding shield and the periphery of the heat coupling portion of the heat sink.

[0005] In some embodiments, the frame body of the shielding fence has a front frame, a rear frame, and two side frames, and the fixing structure includes a plurality of snap-fit structures.

[0006] In some embodiments, the snap-fit structure includes a snap tab integrally formed on the guiding shield and beside the window, and snap protrusions formed on the two side frames of the frame body of the shielding fence and correspondingly snapped with the snap tab. The snap tab has a snap hole, and the snap protrusion has a snap block for snapping into the snap hole of the snap tab.

[0007] In some embodiments, the snap tab further has side bars located on both sides of the snap hole, the snap protrusion further has limiting protrusions located on both sides of the snap bump, and a limiting groove for accommodating the side bars is formed between the snap bump and the limiting protrusions.

[0008] In some embodiments, the heat sink further has a shielding portion formed on this surface and jointly defining a concave groove with the thermal coupling portion and this surface, the concave groove accommodating the two side frames and the rear frame of the shielding fence, and an opening for the snap protrusion to pass through is formed in the shielding portion.

[0009] In some embodiments, the fixing structure includes an adhesive material, and the shielding fence is fixed to the wall of the guiding shielding cover through the adhesive material.

[0010] In some embodiments, the heat sink further has a shielding portion formed on this surface and jointly defining a concave groove with the thermal coupling portion and this surface, the concave groove accommodating at least one of the front frame, the rear frame and the two side frames of the shielding fence.

[0011] In some embodiments, a plurality of the snap-type structures are staggered from each other front and back.

[0093] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0094] Refer to Figures 1 to 5, a first embodiment of the connector assembly 100 of the present invention is applicable to be plugged into a pluggable module 200. The pluggable module 200 includes a housing 201, a plug-in board 202, and a cable 203. The housing 201 includes a plug-in portion 201a. The plug-in board 202 is disposed in the plug-in portion 201a protruding from the plug-in portion 201a, and the plug-in board 202 has a plurality of contact fingers 202a. The cable 203 is disposed in the housing 201 and is mechanically and electrically connected to the plug-in board 202. The connector assembly 100 includes a guiding shield 1, a socket connector 2, a shielding fence 3, a heat sink 4, and two pressing elastic members 5. It should be noted that the numbers of the guiding shield 1, the shielding fence 3, the socket connector 2, the heat sink 4, and the pressing elastic members 5 can each be adjusted according to requirements and can be in a stacked or combined structure, and are not limited to the numbers in this first embodiment.

[0095] The guiding shield 1 is made of metal, for example. The guiding shield 1 can be formed by stamping and bending a metal plate through a mold. The guiding shield 1 extends along a front-rear direction D1 (the arrow indicates the front, and the reverse direction is the rear) and has a top wall 11, a bottom wall 12 spaced oppositely from the top wall 11 along an up-down direction D2 (the arrow indicates the up, and the reverse direction is the down), two side walls 13 spaced oppositely from each other along a left-right direction D3 (the arrow indicates the right, and the reverse direction is the left) and respectively connected to both sides of the top wall 11 and the bottom wall 12, a rear wall 14 located at the rear end and connected to the rear edges of the top wall 11 and the plurality of side walls 13, and a plurality of pins 15 extending downward from the plurality of side walls 13 and adapted to be fixed on a circuit board (not shown) and / or connected to a ground trace. In addition, the guiding shield 1 further has an accommodation space 16 defined by the top wall 11, the bottom wall 12, the two side walls 13, and the rear wall 14 and located inside, a socket 161 located at the front end and communicating with the accommodation space 16 for the pluggable module 200 to be inserted, a window 162 formed on the top wall 11 and extending rearward from the front section of the top wall 11 and communicating with the accommodation space 16, and a bottom opening 163 located behind the bottom wall 12 and communicating with the accommodation space 16.

[0096] The socket connector 2 is covered by the guiding shielding cover 1 through the bottom opening 163, so that the socket connector 2 is disposed at the rear section of the accommodating space 16. In addition, the socket connector 2 is mechanically and electrically disposed on the circuit board. The socket connector 2 has an insulating housing 21 and a plurality of terminals 22. The housing 21 has a plugging slot 211 facing forward. The plurality of terminals 22 are disposed in the plugging slot 211, and their tails (not shown in the figure) are electrically and mechanically connected to the circuit board. After the pluggable module 200 enters the guiding shielding cover 1 from the socket 161, the plugging board 202 protruding from the plugging portion 201a of the pluggable module 200 can be inserted into the plugging slot 211 of the socket connector 2, so that the contact fingers 202a of the plugging board 202 contact the terminals 22 in the plugging slot 211 of the socket connector 2, so that the pluggable module 200 and the socket connector 2 of the connector assembly 100 are docked with each other. In addition, a plurality of grounding members 17 are provided at the socket 161 of the guiding shielding cover 1. The grounding members 17 have a plurality of elastic fingers 171 extending rearward from the socket 161 and distributed on the outer side and the inner side of the guiding shielding cover 1. Among the plurality of elastic fingers 171, those located on the outer side of the guiding shielding cover 1 are used to partially contact a part of a chassis (not shown in the figure) located at the periphery of a mounting hole (not shown in the figure), and those located on the inner side of the guiding shielding cover 1 are used to contact the pluggable module 200.

[0097] The shielding fence 3 is disposed on the top wall 11 of the guiding shielding cover 1 through a fixing structure 6. The material of the shielding fence 3 is a material capable of shielding or absorbing electromagnetic waves. For example, it can be a metal material (such as a solid metal frame, a wire mesh, a metal spring), or a conductive material such as a conductive elastic gasket, conductive rubber, or conductive foam. The shielding fence 3 has a frame body 31 and an opening 32 defined by the frame body 31 and corresponding to the window 162. The opening 32 can be approximately the same size as the window 162, for example. In this first embodiment, the frame body 31 has a front frame 311 located in the front, a rear frame 312 located in the rear, and two side frames 313 connected between the front frame 311 and the rear frame 312 and arranged at intervals along the left-right direction D3. The fixing structure 6 includes a plurality of snap-in structures 61. Each snap-in structure 61 includes a plurality of snap-in pieces 611 formed at the junction of the top wall 11 and the two side walls 13 of the guiding shielding cover 1 and beside the window 162, and a plurality of snap-in protrusions 612 formed on the two side frames 313 of the frame body 31 of the shielding fence 3 and extending outward and respectively corresponding to and snap-connected to the plurality of snap-in pieces 611. In this first embodiment, the plurality of snap-in pieces 611 extend vertically upward along the up-down direction D2, and the plurality of snap-in protrusions 612 extend horizontally along the left-right direction D3, but this is not limiting. Each snap-in piece 611 has a snap-in hole 611a, and each snap-in protrusion 612 has a snap-in bump 612a for snap-connecting to the snap-in hole 611a of the corresponding snap-in piece 611. Through the snap-in holes 611a of the plurality of snap-in pieces 611 and the snap-in bumps 612a of the plurality of snap-in protrusions 612 that are snap-connected to each other, the shielding fence 3 can be fixedly disposed on the top wall 11 of the guiding shielding cover 1. Specifically, each snap-in piece 611 further has two side bars 611b located on both sides of the snap-in hole 611a, and each snap-in protrusion 612 further has two limiting protrusions 612b located on both sides of the snap-in bump 612a. Two limiting grooves 612c for respectively accommodating the two side bars 611b are formed between the snap-in bump 612a and the plurality of limiting protrusions 612b, thereby strengthening the snap-connection strength between the plurality of snap-in pieces 611 and the plurality of snap-in protrusions 612. In addition, in this first embodiment, the plurality of snap-in structures 61 located on the two side frames 313 can be staggered from each other along the front-rear direction D1, for example. Thereby, the assembly between the guiding shielding cover 1 and the shielding fence 3 can be made more stable, and when a plurality of connector assemblies 100 are juxtaposed closely, interference between the snap-in structures 61 of different connector assemblies 100 can be avoided.

[0098] It should be noted that the fixing structure 6 may further include an adhesive material 62 (seeFigure 6 ) The bottom of the shielding fence 3 is fixed to the top wall 11 of the guiding shielding cover 1 by the adhesive material 62. In a variant embodiment, the fixing structure 6 may also only include the adhesive material 62. The adhesive material 62 may be, for example, an adhesive, a double-sided tape or other adhesive material 62.

[0099] Refer to Figures 2 to 3 and Figures 6 to 8 , the heat sink 4 has a substrate 41 formed with a bottom surface 411 and a top surface 412, a plurality of heat dissipation fins 42 that are fastened to each other side by side in the left-right direction D3 and disposed on the top surface 412 of the substrate 41, and a thermal coupling portion 43 that protrudes downward and is disposed on the bottom surface 411 of the substrate 41. The plurality of heat dissipation fins 42 may be, for example, disposed on the top surface 412 of the substrate 41 by welding, but is not limited thereto. The bottom surface 411 of the substrate 41 is disposed on the top wall 11 of the guiding shielding cover 1, the thermal coupling portion 43 passes through the window 162 on the top wall 11 and enters the accommodation space 16, and the entire heat sink 4 and its thermal coupling portion 43 can move relative to the guiding shielding cover 1. It should be noted that although the shielding fence 3 and the heat sink 4 are installed on the top wall 11 in this first embodiment, in other embodiments, the shielding fence 3 and the heat sink 4 may also be installed on the bottom wall 12 formed with the window 162, or two shielding fences 3 and two heat sinks 4 are respectively installed on the top wall 11 and the bottom wall 12 formed with the window 162. Additionally, although in this first embodiment, the thermal coupling portion 43 is directly integrally formed on the substrate 41 to move along with the substrate 41, in other embodiments, the thermal coupling portion 43 may also be an independent element assembled to be movable relative to the substrate 41, or an independent element fixedly assembled to the substrate 41 and moving together with the substrate 41. Furthermore, in this first embodiment, the thermal coupling portion 43 is provided with a thermal conductive pad 44, and the thermal conductive pad 44 can sufficiently fill the seams or gaps of the contact surface to reduce the contact thermal resistance between the contact surfaces. The thermal conductive pad 44 may be, for example, a thermal interface material, and its material may be selected from a combination of materials having, for example, high thermal conductivity, high flexibility, compressibility, insulation, wear resistance and other characteristics, and may be, for example, a material combination of a base material and a phase change material. For example, it may be a structure with two or more layers, and its outer layer base material may be a material having thermal conductivity, lubricity, wear resistance, tear resistance (such as Teflon), and its inner layer material is a phase change material. Additionally, the thermal conductive pad 44 may also simultaneously have an electromagnetic wave shielding effect (EMI Shielding) through a combination change of materials.

[0100] Refer to Figure 2, Figure 3 , Figure 7 and Figure 8 , in this first embodiment, the plurality of pressing elastic members 5 are elastic fasteners and are used to assemble the radiator 4 to the top wall 11 of the guiding shielding cover 1. Each pressing elastic member 5 has an elastic pressing portion 51 that elastically presses against a plurality of heat dissipation fins 42 of the radiator 4 from above, and two assembling portions 52 that extend downward from the left and right ends of the elastic pressing portion 51 and are respectively assembled to two side walls 13 of the guiding shielding cover 1. Specifically, two buckling blocks 131 are formed on each side wall 13 located on both sides of the guiding shielding cover 1, and each assembling portion 52 is formed with a buckling hole 521 that corresponds to and buckles with the buckling block 131 of the corresponding side wall 13. In addition, the radiator 4 further has two positioning grooves 45 formed on the plurality of heat dissipation fins 42 and used for mutual positioning with the elastic pressing portions 51 of the two pressing elastic members 5. It should be noted that although the number of the elastic pressing portions 51 and the assembling portions 52 of the pressing elastic members 5 is one to two in this first embodiment, in other embodiments, the number of the elastic pressing portions 51 and the assembling portions 52 can also be adjusted to any number according to requirements. In addition, the pressing elastic members 5 may not be elastic fasteners and may be replaced with other types of pressing elastic members 5 for pressing on the radiator 4, and this is not limited to this first embodiment.

[0101] Refer to Figure 1 , Figure 7 and Figure 9 , when the pluggable module 200 enters the guiding shielding cover 1 and is docked with the socket connector 2 of the connector assembly 100, the top surface 412 of the plugging portion 201a of the housing 201 of the pluggable module 200 will contact the heat coupling portion 43 of the radiator 4, and will push up the heat coupling portion 43 of the radiator 4 together with the entire radiator 4 upward (see Figure 9 ). Further, due to the reaction force of downward pressing exerted on the radiator 4 by the pressing elastic member 5, the heat coupling portion 43 of the radiator 4 will be closely abutted against the plugging portion 201a of the housing 201 of the pluggable module 200, thereby maintaining the contact relationship between the pluggable module 200 and the radiator 4 to ensure the heat dissipation performance.

[0102] The frame body 31 of the shielding fence 3 is located between the top wall 11 of the guiding shielding cover 1 and the bottom surface 411 of the radiator 4, and surrounds the periphery of the window 162 of the top wall 11 of the guiding shielding cover 1 and the periphery of the heat coupling portion 43 of the radiator 4. Through the shielding fence 3 provided on the top wall 11 of the guiding shielding cover 1 and having the opening 32 corresponding to the window 162, the gap between the top wall 11 of the guiding shielding cover 1 and the bottom surface 411 of the radiator 4 can be shielded, and even when the heat coupling portion 43 of the radiator 4 together with the entire radiator 4 is pushed upward, it can still be shielded around the window 162 of the guiding shielding cover 1 to enhance the electromagnetic shielding effect.

[0103] In this first embodiment, the radiator 4 further has a shielding portion 46 formed on the bottom surface 411 of the substrate 41 and jointly defining a concave groove 47 with the heat coupling portion 43 and the bottom surface 411. The shielding portion 46 is located on the left and right sides and the rear side of the heat coupling portion 43, so that the concave groove 47 is generally U-shaped and accommodates the two side frames 313 and the rear frame 312 of the shielding fence 3. The shielding portion 46 is formed with a plurality of through holes 461 for a plurality of buckling convex portions 612 to pass through and buckle to the corresponding buckling pieces 611. Preferably, as Figure 9 shown, even when the heat coupling portion 43 of the radiator 4 together with the entire radiator 4 is pushed upward by the pluggable module 200, the shielding fence 3 is still partially located in the concave groove 47. Through the shielding portion 46 and the concave groove 47, the shielding fence 3 can be covered, which can enhance the shielding effect and beautify the appearance of the connector assembly 100.

[0104] Refer to Figures 10 to 12 In a second embodiment of the connector assembly 100 of the present invention, the difference from the first embodiment is that the shielding portion 46 of the radiator 4 in the second embodiment is only located at the rear side of the heat coupling portion 43, so that the concave groove 47 is generally in a straight shape and accommodates the rear frame 312 of the shielding fence 3. It should be noted that in other embodiments, the shielding portion 46 of the radiator 4 can also be located on at least any one side of the heat coupling portion 43, so that the concave groove 47 accommodates at least one of the front frame 311, the rear frame 312 and the two side frames 313 of the shielding fence 3.

[0105] In addition, the number of the pressing elastic members 5 in the second embodiment is one, and the pressing elastic member 5 has two elastic pressing portions 51 that elastically press against the top surface 412 of the substrate 41 of the radiator 4 from above and two assembling portions 52 that are connected between the two elastic pressing portions 51 and are respectively assembled to the two side walls 13 of the guiding shielding cover 1. Each assembling portion 52 is formed with two buckling holes 521 that correspond to and buckle to the buckling blocks 131 of the corresponding side wall 13. In addition, the heat dissipation fins 42 of the radiator 4 are integrally extended from the top surface 412 of the substrate 41 in this second embodiment.

[0106] Refer to Figures 13 to 14 , a third embodiment of the connector assembly 100 of the present invention is different from the first embodiment in that the guiding shield 1 of the third embodiment further has a partition wall 18 located between the two side walls 13 and arranged side by side at intervals from the two side walls 13. The guiding shield 1 has two accommodating spaces 16 defined by the top wall 11, the bottom wall 12, the two side walls 13, the rear wall 14 and the partition wall 18 together, two sockets 161 corresponding to and communicating with the two accommodating spaces 16, and two windows 162 formed on the top wall 11 and corresponding to and communicating with the two accommodating spaces 16. The number of the shielding fences 3 and the radiators 4 in the third embodiment is two each. The two shielding fences 3 are respectively arranged on the top wall 11 of the guiding shield 1 through two fixing structures 6. The heat coupling parts 43 of the two radiators 4 respectively pass through the two windows 162 on the top wall 11 and enter the two accommodating spaces 16. And, since the snap-fastening structures 61 on the left and right sides of each fixing structure 6 are staggered from each other along the front-rear direction D1, the snap-fastening structures 61 of the two fixing structures 6 can be prevented from interfering with each other.

[0107] In addition, the elastic pressing part 51 of each pressing elastic member 5 in the third embodiment straddles the two radiators 4 and presses against the two radiators 4. The partition wall 18 is formed with two assembling extension parts 181 that penetrate upward through the top wall 11. The top end of each assembling extension part 181 is formed with an assembling tab 181a. The elastic pressing part 51 of each pressing elastic member 5 is formed with an assembling hole 511 that is buckled with the corresponding assembling tab 181a, thereby strengthening the supporting force provided by the guiding shield 1 to the middle part of the elastic pressing part 51 of the two pressing elastic members 5.

[0108] In summary, the shielding fence 3 arranged on the top wall 11 of the guiding shield 1 of the present invention can shield the gap between the top wall 11 of the guiding shield 1 and the bottom surface 411 of the radiator 4, and even when the heat coupling part 43 of the radiator 4 together with the whole radiator 4 is pushed upward, it can still be shielded around the window 162 of the guiding shield 1 to enhance the electromagnetic shielding effect.

[0109] However, the above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope covered by the patent of the present invention.
